Description

Die Erfindung bezieht sich auf eine einen Abschalwinkel und eine Befestigungsvorrichtung für diesen Abschalwinkel aufweisende Anordnung für eine Betonschalung, z.B. eine Deckenrandabschalung oder Unterzugschalung, wobei der Abschalwinkel in Gebrauchsstellung ein Vertikalprofil und ein auf die obere Fläche eines Trägers auflegbares Horizontalprofil und einen diese beiden Profile miteinander verbindenden schräg verlaufenden Druckstab aufweist.The invention relates to a shuttering angle and a fastening device for this formwork angle Arrangement for concrete formwork, e.g. a ceiling edge formwork or girder formwork, the shuttering angle in the use position a vertical profile and one on the top surface of a support horizontal profile and a diagonally connecting these two profiles together has extending pressure rod.

Bei einer durch die DE-A-40 13 093 bekannten Schalung weist die Befestigungsvorrichtung einen um eine senkrechte Achse im Horizontalprofil schwenkbar gelagerten Dopppelarm auf, der an seinen Enden abwärts gerichtete Klauen aufweist, deren Enden wiederum mit nach innen weisenden Laschen versehen sind, die beim Verschwenken des Doppelarms eine am Träger vorhandene Kante, beispielsweise einen Obergurt eines Holzgitterträgers, untergreifen können. Ein die Achse bildender drehbarer Bolzen weist an seinem oberen Ende ein Schraubengewinde auf, auf das eine sich auf die obere Fläche des Horizontalprofils abstützende Flügelmutter aufgeschraubt ist. Soll der Abschalwinkel auf dem Träger befestigt werden, so wird der Doppelarm zunächst so verschwenkt, daß die Laschen unter eine Kante des Trägers zu liegen kommen. Dann wird die Flügelmutter angespannt, die das Horizontalprofil des Abschalwinkels über geeignete Stützelemente auf die obere Fläche aufpreßt und so den Abschalwinkel auf dem Träger befestigt. Die Höhe der Klauen an dem Doppelarm ist jedoch konstruktiv begrenzt, so daß der Abschalwinkel nur an Holzträgern mit I-Querschnitt befestigt werden kann, deren Obergurt eine bestimmte Höhe nicht überschreitet. In a formwork known from DE-A-40 13 093 the fastening device a about a vertical axis double arm pivoted in the horizontal profile, which has claws pointing downward at its ends, the In turn, the ends are provided with tabs pointing inwards are one on the carrier when pivoting the double arm existing edge, for example an upper chord of a wooden lattice girder, can reach under. An axis forming rotatable bolt has a screw thread at its upper end on which one is on the top surface of the horizontal profile supporting wing nut is screwed on. If the shuttering angle is to be attached to the carrier, so the double arm is first pivoted so that the tabs come to rest under an edge of the beam. Then the Wing nut strained, which the horizontal profile of the shuttering angle via suitable support elements on the upper surface presses on and so the shuttering angle attached to the carrier. However, the height of the claws on the double arm is constructive limited, so that the shuttering angle only on wooden beams with I-section can be attached, the top chord does not exceed a certain height.

Es ist jedoch erwünscht, daß derartige Abschalwinkel nicht nur an Holzträgern befestigt werden können, deren Obergurt unterschiedliche Höhen aufweist, vielmehr sollen bekannte Abschalwinkel auch an aus Kantholz oder dergleichen bestehenden Trägern befestigt werden können, bei denen der Abstand einer Kante, die untergriffen werden kann, von der oberen Fläche des Trägers relativ groß ist. Auch ist bei dieser bekannten Befestigungsvorrichtung umständlich, daß der Drehbolzen zusammen mit dem Doppelarm und den Klauen stets soweit angehoben werden muß, daß die Laschen am unteren Ende der Klauen eine untere Fläche am Träger hintergreifen können. Bei unterschiedlichen Trägern muß diese Höhe jeweils wieder eingestellt werden.However, it is desirable that such shutter angles not can only be attached to wooden beams, the top chord has different heights, rather known Formwork angle also on existing timber or the like Straps can be attached where the distance an edge that can be undercut from the upper surface of the carrier is relatively large. Is also at this known fastening device cumbersome that the pivot pin together with the double arm and the claws always have to be raised so far that the tabs on the bottom Grip a lower surface on the carrier at the end of the claws can. With different beams, this height must in each case can be set again.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Betonschalung, z.B. einer Deckenrandabschalung oder Unterzugschalung eine Befestigung für einen Abschalwinkel zu entwickeln, der bei vielen Trägern unterschiedlicher Höhe eines Obergurtes oder eines Vierkantholzes ohne größere Verstellung angewandt werden kann.The invention has for its object in a concrete formwork, e.g. a ceiling edge formwork or joist formwork to develop a fastening for a shuttering angle, that with many carriers of different heights of an upper chord or a square wood without major adjustment can be.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Befestigungssvorrichtung eine Klemmverbindung mit zwei Schenkeln aufweist, die durch eine Spannvorrichtung kraftschlüssig an die beiden Seitenflächen des Trägers anpreßbar sind.This object is achieved according to the invention in that the fastening device is a clamp connection with two Has legs that are non-positively by a clamping device can be pressed against the two side surfaces of the carrier are.

Zwar ist durch die US-A-3 648 962 eine Verbindungsvorrichtung mit einer Klemmvorrichtung bekanntgeworden, die eine Verbindung zwischen einer Querstrebe zwischen senkrechten Trägern (Spalte 1 Zeile 20-25) eines Schalelementes für eine Schalung einer Betonwand und einem zur Verstärkung des Schalelementes parallel zur Schalfläche angeordneten Träger herstellt. Diese Verbindungsvorrichtung weist einen waagrechten Stab auf, an dessen der Querstrebe zugewandtem Ende eine Klemmverbindung angeordnet ist. Diese weist, wie Fig. 6 zeigt, ein Teil auf, das durch einen Keil, der in einem mit dem Stab fest verbundenen Teil geführt ist, gegen die obere Fläche der Querstrebe gedrückt werden kann. Dabei federt auch ein waagrecht verlaufender Plattenabschnitt mit, der über einen senkrecht verlaufenden Wandabschnitt mit dem Stab verbunden ist. Das von der Querstrebe abgewandte Ende dieser Verbindungsvorrichtung greift an dem Aussteifungsträger an und hält diesen über Zwischenhölzer an der Schalung.US-A-3 648 962 is a connector become known with a clamping device that connects between a cross strut between vertical beams (Column 1, lines 20-25) of a formwork element for formwork a concrete wall and one to reinforce the formwork element produces beams arranged parallel to the formwork surface. This connecting device has a horizontal Rod, at the end facing the cross strut one Clamping connection is arranged. This has, as Fig. 6th shows a part by a wedge that is in a with the rod firmly connected part is guided against the upper Surface of the cross strut can be pressed. It springs also a horizontally running plate section with the over a vertical wall section with the rod connected is. The end of the cross strut facing away from it Connection device engages the stiffening girder and holds it to the formwork using intermediate timbers.

Kein Teil dieser Verbindungsvorrichtung ist mit einem Abschalwinkel vergleichbar. Wegen der auch völlig anderen Aufgabe dieser Verbindungsvorrichtung sind auch die Kräfte, die diese Verbindungsvorrichtung aufnehmen muß, völlig von den Kräften verschieden, die ein Abschalwinkel auf die Unterlage ableiten muß. Daher fehlt auch der bei Abschalwinkeln stets notwendige schräge Druckstab. Der senkrecht verlaufende Wandabschnitt nimmt keinen Betondruck auf. Dieser wird über den Träger und die Zwischenhölzer auf den Versteifungsträger abgeleitet. Diese Verbindungsvorrichtung liegt dem Anmeldungsgegenstand völlig fern.No part of this connection device is with a shuttering angle comparable. Because of the completely different task this connecting device are also the forces that this connection device must accommodate completely from the Forces different, which a formwork angle on the base must derive. Therefore, there is always a lack of shuttering angles necessary oblique pressure rod. The vertical one Wall section does not take up any concrete pressure. This is about the beam and the intermediate wood on the stiffening beam derived. This connecting device is the subject of the application completely distant.

Die erfindungsgemäße Befestigungsvorrichtung weist kein zur Funktion nötiges Teil auf, mit dem eine untere Fläche oder eine entsprechende Kante des Trägers untergriffen werden muß, sie ist daher weitgehend unabhängig von der Höhe des Trägers und ohne Verstellen einsetzbar, da sie lediglich an den Seitenflächen, nicht aber an der Unterfläche eines Trägers angreift. Versuche haben ergeben, daß eine solche, im wesentlichen kraftschlüssige Verbindung zwischen Abschalwinkel und Träger für die Funktion eines Abschalwinkels völlig ausreichend ist.The fastening device according to the invention has no Function necessary part with which a lower surface or a corresponding edge of the carrier can be reached must, it is therefore largely independent of the amount of Carrier and can be used without adjustment, since it is only on the side surfaces, but not on the lower surface of a beam attacks. Experiments have shown that such, in essential positive connection between shuttering angle and carrier for the function of a shutter angle entirely is sufficient.

Bei Ausführungsformen der Erfindung weisen die Schenkelenden an den den Seitenflächen des Trägers zugewandten Flächen Vorsprünge auf, die sich beispielsweise bei Verwendung von Trägern aus Holz in die Holzoberfläche der Seitenflächen des Trägers etwas eindrücken und so diese Verbindung zwischen Träger und Befestigungsvorrichtung besonders stabil gestalten. Wo dies nicht erforderlich ist, können solche Vorsprünge auch fehlen.In embodiments of the invention, the leg ends have on the surfaces facing the side surfaces of the carrier Projections on, for example, when using Wooden beams in the wooden surface of the side surfaces of the Press something into the wearer and so this connection between Make the carrier and fastening device particularly stable. Where this is not necessary, such protrusions can be used also missing.

Bei einer zweckmäßigen Ausführungsform der Erfindung weist die Befestigungsvorrichtung zwei Schenkel und ein diese Schenkel verbindendes Joch auf, ist also im Prinzip etwa U-förmig, wobei aber die Schwenkpunkte der Schenkel am Joch in einem Abstand voneinander angeordnet sind. Ist dieser Abstand so groß wie der Abstand der beiden Seitenflächen des Träger voneinander, so legen sich beim Spannen der Klemmverbindung die Enden der Schenkel, parallele Seitenflächen vorausgesetzt, mit ihrer ganzen Fläche an den Seitenflächen an. Weicht dieser Abstand der Schwenkpunkte von dem Abstand der Seitenflächen des Trägers ab, so kann es zweckmäßig sein, die an den Seitenflächen des Träger angreifenden Flächen der Schenkel mit einer leichten Rundung zu versehen, so daß der erfindungsgemäße Abschalwinkel auch in Verbindung mit Trägern verwendet werden kann, bei denen nicht nur ihre Höhe unterschiedlich ist, sondern auch ihre Breite.In an expedient embodiment of the invention the fastening device two legs and one this Leg connecting yoke on, is in principle approximately U-shaped, but where the pivot points of the legs on the yoke in are spaced from each other. Is this distance as large as the distance between the two side surfaces of the Carriers from each other, so lie down when tensioning the clamp connection the ends of the legs, provided parallel side faces, with their entire surface on the side surfaces. Does this distance of the pivot points deviate from the distance of Side surfaces of the carrier, it may be appropriate the surfaces of the To provide legs with a slight curve so that the shuttering angle according to the invention also in connection with beams can be used where not only their height is different, but also their breadth.

Die Befestigungsvorrichtung kann bei Ausführungsformen der Erfindung durch eine separate Klammer gebildet sein. Dies hat den Vorteil, daß für verschiedene Anwendungsfälle optimal hierauf abgestimmte Klammern bereitgehalten werden können. Für die häufigen Holzbreiten 8-10 cm ist nur eine Klammer erforderlich. Dabei kann diese Klammer ebenfalls eine U-Form aufweisen und bei Ausführungsformen der Erfindung das die beiden Schenkel verbindende Joch federnd ausgebildet sein, so daß die Schenkel der durch die Spannvorrichtung auferlegten Schwenkbewegung ohne weiteres folgen können. Diese Ausführungsform der Erfindung kann dahingehend weiter ausgebildet sein, daß diese Feder eine S-Form aufweist, so daß sie bei großer Festigkeit einen verhältnismäßig großen Federweg aufweist und damit den Schenkeln auch einen verhältnismäßig großen Schwenkwinkel, gegebenenfalls gegen Federwirkung, erlaubt. Bei anderen Ausführungsformen der Erfindung sind die Schenkel der Klammer selbst federnd ausgebildet. In diesem Falle ist das die beiden Schenkel verbindende Joch steif, so daß ein Spannen der Spannvorrichtung, die gegebenenfalls auf halber Länge der Schenkel angreifen kann, keine Veränderung der Jochlänge hervorruft, sondern nur eine Bewegung der Schenkelenden gegeneinander.The fastening device can be used in embodiments of the Invention be formed by a separate bracket. This has the advantage that it is optimal for different applications matching brackets can be kept ready. For the common wood widths 8-10 cm there is only one bracket required. This bracket can also have a U-shape have and in embodiments of the invention the yoke connecting the two legs is resilient be so that the legs of the by the jig imposed swivel movement can follow easily. This embodiment of the invention can go further in that regard be designed that this spring has an S-shape, so that they have a relatively large strength Has spring travel and thus the legs also a relative large swivel angle, possibly against spring action, allowed. In other embodiments of the invention are the legs of the clip itself resilient. In this case it is the one connecting the two legs Yoke stiff so that tensioning of the tensioning device, who attack half the length of the legs if necessary can, does not cause a change in the yoke length, but only a movement of the leg ends against each other.

Bei anderen Ausführungsformen der Erfindung ist die Befestigungsvorrichtung jedoch in den Abschalwinkel integriert, dessen Vertikalprofil einen U-förmigen Querschnitt aufweist. Dabei sind die Schenkel des U-förmigen Querschnitts über die Ansatzstelle des Horizontalprofils hinaus nach unten verlängert und diese Schenkel sind zumindest auf ihrem verlängerten Abschnitt gegeneinander beweglich. Eine Spannvorrichtung preßt diese Verlängerungen an die Seitenflächen des Trägers an. Dabei üben die über die Ansatzstelle des Horitonzalprofils hinaus nach oben ragenden Schenkelabschnitte die übliche Funktion des Abschalwinkels aus, sie dienen nämlich zur Anlage der Schalungsbretter der Betonschalung oder der Abstützung eines anderen Teiles der Schalung wie z.B. eines Geländerpfostens und zur Auflage der Deckenschalung.In other embodiments of the invention is the fastening device however integrated in the shuttering angle, whose vertical profile has a U-shaped cross section. The legs of the U-shaped cross section are over the Starting point of the horizontal profile extended downwards and these thighs are at least on their elongated ones Section movable against each other. A jig presses these extensions onto the side surfaces of the wearer on. They practice over the starting point of the horitonal profile the upward projecting leg sections Function of the shut-off angle, they are used for Installation of the formwork boards of the concrete formwork or the support another part of the formwork, e.g. one Railing post and for laying the ceiling formwork.

Die Verlängerung der Schenkel des Horizontalprofils nach unten kann so gewählt sein, daß ihre Länge für die meisten Anwendungsfälle geeignet ist. Bei Ausführungsformen der Erfindung sind jedoch diese Schenkel des Vertikalprofils gegenüber dem Horizontalprofil längs verschiebbar geführt, so daß die Länge der über die Ansatzstelle des Horizontalprofils hinaus nach unten und nach oben ragenden Verlängerungen einstellbar ist. The extension of the legs of the horizontal profile downwards can be chosen so that its length for most applications suitable is. In embodiments of the invention however, these legs of the vertical profile are opposite guided horizontally displaceable so that the length of the starting point of the horizontal profile Extensions projecting downwards and upwards is.

Bei der in den Figuren 1 und 2 dargestellten Ausführungsform der Erfindung weist ein Abschalwinkel ein Horizontalprofil 1 und ein an dessen Ende starr verbundenes, vorzugsweise verschweißtes Vertikalprofil 2 auf. Diese beiden Profile sind durch einen Druckstab 3 miteinander verbunden. Diese Teile bestehen vorzugsweise aus Metall, die einzelnen Teile können miteinander verschweißt oder als Gußteil, vorzugsweise als Aluminiumguß, hergestellt sein. Das Horizontalprofil weist an seiner Unterseite Rippen 4 auf, mit denen es auf der oberen Fläche 5 eines Obergurtes eines Holzgitterträgers 6 oder auf der oberen Fläche 7 eines Kantholzes 8 aufliegt. In the embodiment shown in Figures 1 and 2 According to the invention, a shuttering angle has a horizontal profile 1 and a rigidly connected, preferably welded, end Vertical profile 2 on. These two profiles are connected to each other by a push rod 3. These parts are preferably made of metal, the individual parts can welded together or as a casting, preferably as Cast aluminum. The horizontal profile points on its bottom ribs 4, with which it is on the top Surface 5 of an upper chord of a wooden lattice girder 6 or rests on the upper surface 7 of a square timber 8.

Die Befestigung des Abschalwinkels 1, 2 an dem Holzgitterträgers 6 erfolgt durch eine Klammer 9, die zwei Schenkel 10 und 11 aufweist, die an ihrem von der Schalung abgewandten Ende durch eine S-förmige Feder 12 zusammengehalten werden und an ihrem vorderen Ende Platten 13 und 14 tragen, die an ihrer einander zugekehrten Fläche kleine Vorsprünge 15 aufweisen. An der Innenseite der Feder 12 ist ein Bolzen 16 befestigt, mit dem die ganze Klammer 9 in einer entsprechenden Öffnung im Druckstab 3 in den Abschalwinkel eingehängt werden kann.The fastening of the shuttering angle 1, 2 to the wooden lattice girder 6 is carried out by a clamp 9, the two legs 10 and 11, which on their facing away from the formwork End are held together by an S-shaped spring 12 and wear plates 13 and 14 at their front end have small projections 15 on their mutually facing surface. A bolt 16 is fastened to the inside of the spring 12, with which the whole bracket 9 in a corresponding Opening in the pressure rod 3 can be hooked into the shuttering angle can.

Die beiden Schenkel 10 und 11 sind etwa in der Mitte ihrer Länge durch eine Schraubverbindung 17 miteinander verbunden, von der lediglich ihr Außenmantel dargestellt ist. Am äußeren Ende der Schraubspindel befindet sich eine Flügelmutter 18, mit der die Maulweite zwischen den Platten 13 und 14 eingestellt werden kann.The two legs 10 and 11 are approximately in the middle of it Length connected by a screw connection 17, of which only their outer jacket is shown. On the outside There is a wing nut at the end of the screw spindle 18, with which the mouth width between the plates 13 and 14th can be adjusted.

Wird die Schraubspindel 17 angezogen, so werden die Platten 13 und 14 an die Seitenflächen 19 des Obergurtes des Holzgitterträgers 6 angepreßt. Über den die Klammer mit dem Abschalwinkel verbindenden Bolzen 16 und/oder über Schrägflächen 40, 41 an den Schenkeln 10, 11 wird hierdurch der Abschalwinkel fest in seiner Position gehalten.If the screw 17 is tightened, the plates 13 and 14 on the side surfaces 19 of the top chord of the wooden lattice girder 6 pressed. Over which the bracket with the shuttering angle connecting bolt 16 and / or over inclined surfaces 40, 41 on the legs 10, 11 thereby the shuttering angle held firmly in place.

In dem Horizontalprofil 2 befinden sich noch Löcher 20, durch die Nägel, Schrauben oder dergleichen Befestigungsmittel eingeschlagen werden können, um das Horizontalprofil 2 in den Ausnahmefällen, in denen man befürchtet, daß die Befestigung des Abschalwinkels durch die Klammer 9 die von der Schalung auf das Vertikalprofil 2 ausgeübte Kraft nicht ganz aufnehmen kann, zusätzlich noch mit dem Holzgitterträger 6 zu verbinden.There are still holes 20 in the horizontal profile 2, through the nails, screws or the like fasteners can be driven to the horizontal profile 2 in exceptional cases where it is feared that the fortification of the shuttering angle through the bracket 9 which of the Formwork on the vertical profile 2 force not quite can also accommodate with the wooden lattice girder 6 connect to.

Das Vertikalprofil hat bei dieser Ausführungsform der Erfindung einen U-förmigen Querschnitt, das Joch 21 des Querschnitts ist starr mit den Schenkeln 22 des Querschnitts verbunden. An ihren der Schalung zugewandten Rändern weisen die Schenkel 22 rechtwinklig abgewinkelte Randstreifen 23 und 24 auf, die zur Anlage an eine ebene Schalung dienen. An der Innenfläche der Schenkel 22 und anschließend an die Randstreifen 23 und 24 sind an diesen Rändern Schrägflächen 25 vorgesehen, die zur Anlage an einer Schalungsecke dienen. Der erfindungsgemäße Abschalwinkel kann daher sowohl zur Abstützung einer ebenen Schalung als auch zur Abstützung einer Schalungsecke dienen, so daß ein zweiter Abschalwinkel an der Schalungsecke eingespart wird.The vertical profile has in this embodiment of the invention a U-shaped cross section, the yoke 21 of the cross section is rigid with the legs 22 of the cross section connected. Point at their edges facing the formwork the legs 22 edge strips 23 angled at right angles and 24, which are used to abut a level formwork. On the inner surface of the legs 22 and then to the Edge strips 23 and 24 are inclined surfaces at these edges 25 are provided, which are used to abut a formwork corner. The shuttering angle according to the invention can therefore be used both for support a level formwork as well as to support one Formwork corner serve, so that a second formwork angle the formwork corner is saved.
